Anticorrosive paint applied to surfaces of aluminum alloy materials

Abstract

The invention discloses anticorrosive paint applied to surfaces of aluminum alloy materials. The anticorrosive paint comprises the following components in parts by weight: 30 to 50 parts of thermosetting acrylic resin, 20 to 40 parts of epoxy resin, 10 to 20 parts of amino resin, 10 to 20 parts of vinylidene chloride resin, 10 to 20 parts of chlorinated rubber, 5 to 10 parts of mica powder, 5 to 10 parts of sodium nitrite, 1 to 5 parts of tin dimethyl, 5 to 15 parts of kaolin, 1 to 5 parts of hydroxyethyl methyl cellulose, 1 to 5 parts of pigment, 1 to 5 parts of xylene, and 5 to 10 parts of silicon oil. The anticorrosive paint applied to the surfaces of the aluminum alloy materials, disclosed by the invention, is applied to the aluminum alloy materials, and can greatly improve performances of the aluminum alloy materials of corrosion resistance, oxidation resistance and the like to prolong the service life of the aluminum alloy materials.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion paint, and in particular relates to an anti-corrosion paint coated on the surface of an aluminum alloy material. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. The density of aluminum alloy is low, but its strength is relatively high, which is close to or exceeds that of high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry, and its usage is second only to aluminum alloy. Yu steel. However, the wear resistance and corrosion resistance of most aluminum products exposed outdoors are not very satisfactory, especially the aluminum doors and windows used...

Problems solved by technology

However, the wear resistance and corrosion resistance of most aluminum products exposed outdoors are not very satisfactory, especially the aluminum doors and windows used in people's daily life, aluminum railings and handrails in public places, etc. In the environment exposed to wind, sun and rain, the surface is corroded, oxidized, and then broken and damaged, which greatly shortens its service life
